Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616258, here are decompositions:

11 + 8616247 = 8616258
17 + 8616241 = 8616258
37 + 8616221 = 8616258
41 + 8616217 = 8616258
59 + 8616199 = 8616258
61 + 8616197 = 8616258
71 + 8616187 = 8616258
89 + 8616169 = 8616258

Showing the first eight; more decompositions exist.
